A small room on the seventh floor of City Hall just might hold the key to easing Boston drivers' frustrations over congested city streets.
Amid the screens with images from live traffic cameras is one that shows a constantly refreshing feed of information from Waze, the GPS app that lets users report road conditions and accidents.
"We're able to track in real time now how traffic is in various parts of the city like never before," said Dan Koh, Mayor Martin J. Walsh's chief of staff.
Based on reports from drivers through the app along with video feeds, engineers in the Traffic Management Center make constant adjustments to traffic lights. On Wednesday, for example, an engineer made a green light a few seconds longer on Commonwealth Avenue because turning cars were blocked on the Green Line tracks.
The city announced a partnership with Waze last month, and has been using it behind the scenes to flag traffic jams. Soon, the city hopes, the Waze data will be put to greater use.
"We can monitor speeds from them on different streets," said Peter Ganong, the city's special assistant for data analytics. "What you can see (from Waze data) is traffic speeding up and then there's a snowstorm and then it's slowing."
Ganong said insights like that could help with decisions such as which roads to prioritize for snow removal. And that's just the tip of the iceberg when it comes to the potential of the data from Google-owned Waze.
"Waze has a pothole feature," he said. "Could we make it that when a Waze user reports a pothole, it goes directly to public works?"
